A theory discussed in your textbook states that the deterioration of cognitive abilities associated with Alzheimer's disease is caused by:
A) the depletion of dopamine in the prefrontal cortex.
B) the buildup of proteins inside and outside of neurons that disrupt normal functioning.
C) the creation of inappropriate synaptic connections between neurons.
D) the inactivation of glutamate receptors.
Answer: B
Rationale: According to one theory, Alzheimer's disease is possibly due to amyloid plaques, proteins that clump together in the spaces between neurons, interrupting their normal activity. In addition, another type of protein (tau) builds up and forms tangles within nerve cells, which severely disrupts their structural integrity and functioning.
